    These underground tanks are filament wound by the technically advanced chop hoop filament winding process (patented) which was chosen after careful investigation proved it produced the most desirable GRP underground tanks. This process produces not only circumferential strength as found in helical wound tanks, but also longitudinal strength. The interlaminar shear strength permits tanks to be cut for manholes and pipework without any undue loss in strength.

    The manufacturing process is carefully monitored with a digital read out system. Chopping glass, winding glass, the resin-rich inner layer and main laminate resins are kept within specification parameters thus minimising human error. Each tank has a smooth moulded resin-rich corrosion barrier inner layer and an external resin-rich water penetration barrier. These layers can incorporate special resins to meet specific applications where the contents are highly corrosive or a potable water approved resin system is required or where surrounding soil is heavily contaminated.

    Quality control procedures require each tank to be carefully inspected and tested. Ultrasonic thickness readings, material content weights, etc are checked and recorded against the tankand#8217s unique serial number. Additional periodic laminate. Testing is carried out by independent testing facilities including stress and strain analysis and also physical property tests to meet specific design criteria. Being manufactured in glass reinforced plastics, underground tanks are light, easy to handle and easy to install. They are not susceptible to rust, exhibit excellent corrosion resistant properties and have a life expectancy in excess of 50 years. The smooth internal moulded finish provides good flow characteristics and enables easy desludging and cleaning operations.
